* Repo copy libpthreads to libkse.David E. O'Brien2007-10-096-670/+0
| | | | | | | | | This introduces the WITHOUT_LIBKSE nob, and changes WITHOUT_LIBPTHREADS to mean with neither threading libs. Approved by: re(kensmith) Notes: svn path=/head/; revision=172492

* Apply a second fix for stack alignment with libkse. This time, enter thePeter Wemm2003-12-051-2/+2
| | | | | | | | | | | | | | UTS with the stack correctly aligned. Also, while here, use an indirect jump rather than the pushq/ret hack. This fixes threaded apps that use floating point for me, although it hasn't solved all the problems. It is an improvement though. Preservation of the 128 byte red zone hasn't been resolved yet. Approved by: re (scottl) Notes: svn path=/head/; revision=123155
* Use amd64_set_fsbase() instead of calling sysarch() directly.Peter Wemm2003-10-231-6/+1
| | | | Notes: svn path=/head/; revision=121409
* Update context code for my last ABI breakage of mcontext. I'm worriedPeter Wemm2003-10-171-7/+8
| | | | | | | | | | about the fpu code here. It should be using fxsave/fxrstor instead of saving/restoring the control word. The SSE registers are used a lot in gcc generated code on amd64. I'm not sure how this all fits together though. Notes: svn path=/head/; revision=121163
* Make KSE_STACKSIZE machine dependent by moving it from thr_kern.c toMarcel Moolenaar2003-09-191-1/+2
| | | | | | | | | pthread_md.h. This commit only moves the definition; it does not change it for any of the platforms. This more easily allows 64-bit architectures (in particular) to pick a slightly larger stack size. Notes: svn path=/head/; revision=120263
* Remove a comment that questioned why the size of the FPUDaniel Eischen2003-09-161-10/+1
| | | | | | | | | | | | | | state for amd64 was twice as large as necessary. Peter recently fixed this, so the comment no longer applies. Also, since the size of struct mcontext changed, adjust the threads library version of get&set context to match. FYI, any change layout/size change to any arch's struct mcontext will likely need some minor changes in libpthread. Notes: svn path=/head/; revision=120108
* Don't assume sizeof(long) = sizeof(int) on x86; use intDaniel Eischen2003-09-031-3/+11
| | | | | | | | | | | | | | | instead of long types for low-level locks. Add prototypes for some internal libc functions that are wrapped by the library as cancellation points. Add memory barriers to alpha atomic swap functions (submitted by davidxu). Requested by: bde Notes: svn path=/head/; revision=119723

* Rethink the MD interfaces for libpthread to account forDaniel Eischen2003-08-054-167/+280
| | | | | | | | | | | | archs that can (or are required to) have per-thread registers. Tested on i386, amd64; marcel is testing on ia64 and will have some follow-up commits. Reviewed by: davidxu Notes: svn path=/head/; revision=118510

* Use FSBase to map kse, GCC generates code which uses %fs to access TLS data.David Xu2003-07-311-4/+4
